The New Innovator Award occupies a distinctive niche in the NIH funding landscape. Rather than requiring preliminary data or a conventional track record, the program seeks out scientists whose ideas are considered transformative precisely because they depart from established approaches. Daniela Friedman, the Arnold School’s associate dean for research and leadership development, described the recognition as extremely well deserved, noting that since joining the school Shi has built an outstanding research program and distinguished herself as an innovative investigator whose work has the potential to reshape her field. For a researcher who has been on the faculty for only a short time, the award signals both the ambition of the science and the confidence the institute has placed in it.

Shi’s path to this project began far from South Carolina. She studied preventive medicine at Shanghai Jiao Tong University in China, where her involvement in tobacco control and other public health research projects led her to a realization that would define her career: improving health requires addressing not only diseases themselves but also the social and behavioral factors that shape how people live. That conviction deepened during an intervention project for people living with HIV in China. Although antiretroviral therapy has transformed HIV from a fatal diagnosis into a manageable chronic condition, Shi observed firsthand how many patients continued to struggle with stigma, fear of disclosure, and discrimination. Even individuals who were effectively controlling the virus medically tended to isolate themselves from family and friends, a pattern that convinced her that biomedical advances alone are not enough and that social and structural barriers must be confronted alongside them.

That experience brought her to the Arnold School, where she enrolled in the doctoral program in health promotion, education, and behavior and later completed a postdoctoral fellowship with the department and the South Carolina SmartState Center for Healthcare Quality. During that period she worked closely with faculty members Xiaoming Li and Xueying Yang, whom she credits as exceptional mentors who encouraged her to ask meaningful research questions, think creatively, and pursue innovative approaches that combine big data and artificial intelligence to advance HIV prevention and care. She has said their guidance was instrumental in her development as an independent researcher, fostering an environment of collaboration, curiosity, and innovation while emphasizing that research should ultimately improve people’s lives. It is also the community she built there, she explains, that drew her to remain at the Arnold School as a faculty member.

The new project brings together the threads of that training into a single, data-intensive research program. Shi and her team will draw on the NIH’s All of Us Research Program, one of the largest and most diverse health data resources ever assembled, which offers researchers access to longitudinal health information from hundreds of thousands of participants across the United States. Using advanced computational techniques, including machine-learning tools, the team will analyze how patterns of sexually transmitted infections relate to HIV risk and to HIV treatment outcomes over time. The analytical challenge is considerable: STI diagnoses arrive in clinical systems as scattered events, and connecting them to downstream HIV outcomes requires models that can capture multilevel social, structural, and clinical determinants of health simultaneously.

The scientific rationale for the project rests on a well-documented but underexploited relationship. Sexually transmitted infections are known to biologically increase the risk of acquiring HIV, and they may also signal lapses in engagement with HIV care among people already living with the virus. Yet, as Shi points out, STI data remains markedly underutilized by healthcare systems and researchers when it comes to predicting who may be at higher risk of HIV infection or adverse HIV-related health outcomes. In most clinical settings, an STI diagnosis is treated as a discrete event to be treated and closed, rather than as a signal that could trigger risk stratification, intensified prevention counseling, pre-exposure prophylaxis evaluation, or re-engagement efforts. Her project aims to close that gap by turning routinely collected clinical data into actionable predictive insight.

The stakes of better prediction are substantial. Of the roughly 1.1 million Americans living with HIV, an estimated 13 percent are unaware of their status, 25 percent do not receive care, and 35 percent are not virally suppressed. Each of those gaps represents a point at which the care continuum fails both the individual and public health, since unsuppressed viral load sustains transmission risk while untreated infection progresses. The extraordinary advances of the past three decades in HIV treatment, including reduced transmission achieved through careful management and modern prevention measures, mean that these numbers do not have to be what they are. What is missing, Shi argues, is a systematic way for clinicians to identify which patients need additional support and when. Her findings are intended to help clinicians do exactly that, and to give other scientists and healthcare providers a foundation for developing more effective strategies for HIV prevention and care.

Technically, the project sits at the intersection of infectious disease epidemiology, behavioral science, and data science. By training machine-learning models on the rich, longitudinal All of Us dataset, the team hopes to detect combinations of STI histories, demographic characteristics, social determinants, and clinical indicators that reliably precede HIV acquisition or poor treatment outcomes. Such models, if validated, could eventually be embedded in electronic health record systems as risk-stratification tools, flagging patients who warrant proactive outreach. The guidelines Shi’s team plans to develop for healthcare providers will translate these statistical findings into concrete clinical workflows, addressing the persistent divide between what population data can reveal and what individual practitioners can act upon during a routine visit.

Beyond its immediate clinical aims, the project reflects a broader vision of prevention that Shi has carried since her early days in preventive medicine: one in which social context, stigma, and structural barriers are treated as measurable, modifiable components of risk rather than as background noise. Her own trajectory, from studying preventive medicine in China to leading federally funded research at a major American research university, is one she hopes will encourage other early-career researchers and international scholars to pursue ambitious ideas with the potential for meaningful public health impact. The award, by its design, rewards exactly that kind of trajectory, betting on investigators whose careers are just taking shape and whose questions are still unconventional.

Looking ahead, Shi describes the Arnold School and the Center for Healthcare Quality as a unique environment where expertise in public health, clinical research, and data science converge. She intends to use the New Innovator Award to build an independent research program that leverages large-scale data and artificial intelligence to improve HIV prevention and care, while eventually extending her methods to other infectious diseases and health disparities. She also plans to invest in the next generation of the field, mentoring students and collaborating across disciplines to translate research findings into real-world impact. For a scientist whose formative insight was that data alone is never enough, the project she has now begun represents an attempt to prove the converse as well: that when large-scale data is joined to an understanding of human behavior and social barriers, prediction can become prevention.
